摘要
目的 探究噪声暴露者的噪声下信噪比损失(SNR loss)与耳蜗电图的关系及其对隐性听力损失的辅助诊断价值。方法 选取有噪声暴露史的工人41例(41耳),分别进行纯音测听、声导抗、噪声下的言语识别以及耳蜗电图测试,依据噪声下言语识别能力分为两组,A组:SNR loss<0(19耳),B组:SNR loss≥0(22耳),分析两组耳蜗电图的差异。结果 噪声下言语识别测试结果显示,A、B两组受试者的信噪比损失差异有统计学意义(P<0.05);耳蜗电图结果显示,在96、90、80 dB nHL三个刺激强度下A组AP振幅大于B组,差异有统计学意义(P<0.05);在96、90、80、70、60 dB nHL五个刺激强度下B组SP振幅大于A组,差异有显著统计学意义(P<0.001);在96、90、80、70 dB nHL四个刺激强度下,B组SP/AP振幅比大于A组,差异有统计学意义(P<0.05)。结论 信噪比损失<0与≥0的噪声暴露者耳蜗电图SP/AP振幅比在不同声强下有显著差异。
